3. ANALOGREPORT is the function block responsible for reporting the analog values. Each
instance of ANALOGREPORT function block has 24 analog channels with the following setting
parameters; where X is a number from 1 to 24:

PhasorXUseFreqSrc : Enables/Disables the contribution of Phasor channel X in
automatic frequency source selection by choosing
connected preprocessor block delivers the frequency data, derived from the analog
input AC voltage values, to the respective voltage phasor channel. Every phasor channel
has a user-settable parameter (
data for reporting to the PDC client. It is very important to set this parameter to
the voltage-connected phasor channels. There is an automatic frequency source
selection logic to ensure an uninterrupted reporting of the system frequency to the PDC
client. More information is available under the section
AnalogXRange : This parameter defines a range between -AnalogXRange and
+AnalogXRange for AnalogX value. The range will be used by the IED to apply a proper
scale factor to the AnalogX values when

of the configuration frame 3 organization defined in IEEE C37.118.2 message format. The
AnalogXRange value can be a number between 3277.0 and 10000000000 . This setting is
only important if the AnalogDataType setting is selected as
available under the section
AnalogXUnitType : Unit type for analog signal X. It refers to the 4-byte ANUNIT field of
the configuration frames 1, 2 organization defined in IEEE C37.118.2 message format.
